DETERMINATION OF HEAVY METALS IN THE MUSCLES OF SOME FISH SPECIES FROM LAKES IN NORTH-EASTERN POLAND

Lead, cadmium and total mercury concentrations have been determined in the muscle of six fish species: roach (Rutilus rutilus L.), bream (Abramis brama L.), perch (Perca fluviatilis L.), pike (Esox lucius L.), vendace (Coregonus albula L.) and whitefish (Coregonus lavaretus L.) from selected lakes in North-Eastern Poland (Łańskie, Pluszne, Dłużek and Maróz), caught over the period October 1999 to October 2000. Levels of Pb and Cd have not differed in fish of different feeding type, with the exception of cadmium in fish from Lake Łańskie (p≤0.01). Generally, the higher concentrations of total mercury were found in predatory than non-predatory fish (p≤0.01). Only some specimens (perch of the Dłużek and Maróz lakes and roach of the Dłużek Lake) had Pb levels exceeding 0.2 mg/kg. The Hg concentration in muscle of some perch (except from Lake Łańskie) exceeded the Polish safety limit of 0.5 mg/kg.
